Dredge Ship Discharge Upgrade

A major building products supplier needed to update a number of dredging ships discharge system. The existing DC drives were obsolete and the control algorithm did not give precise control resulting in long discharge times and unpredictable control of the discharge buckets.

An engineering study determined that the original DC motors were in good condition, however the DC drive converters, AC conveyor invertors, conveyor soft starts along with the Process PLC required replacing.
